The vacuum level is determined by the pressure differential between the evacuated volume and the surrounding atmosphere. Several units of measure can be used. Most refer to the height of a column of mercury â usually inches of mercury (in.-Hg) or millimeters of mercury (mm-Hg).
Our vacuum pumps and pressure blowers can provide vacuum as low as .2 micron to pressures up to 100 PSI. Thousands of vacuum, air and gas applications exist. Customized options and systems are available.
